Was wondering that myself. Some recycling plants that utilize single stream are also saying its getting less efficient since so much has to be incinerated at high levels and chemicals added. Same could go for meat as you say. I imagine the energy alone to create this could be problematic. Also added nutrients and vitamins and acquiring them are going to add to that.

I would be ok with this, too. And if it's not dairy, I could eat it after having real hamburger, too!

So with kosher diets, you can't have dairy and meat in your stomach at the same time? I thought dairy and meat could not touch each other outside your body. How long did it take you to learn all of this? Seems complicated.

It is not a matter of "in the stomach." They cannot be cooked together, eaten together, much less at the same meal. (See more below.)

There are varying opinions, but the general halachic consensus is that after dairy, you have to wait about an hour before eating meat; whereas after meat, you have to wait six hours before eating dairy again.

That, too. In fact, there must be separate, dedicated utensils for dairy and meat. Parve, or food that is neither dairy nor meat, can but need not have dedicated utensils, as such food can be eaten with either. (E.g., fruit, vegetables, grains.)

"Parve" includes eggs and fish, by the way. With fish, though, while it can be eaten at the same meal as meat, it cannot be on the same plate, so if you are at a kosher home for a meal, what you think of as the "salad plate" (which it also is) would probably be referred to as the "fish plate," and would be collected before the meat is served.

You have no idea. There are whole books. I am still learning, and have been for around 8 years or so. But so are the experts ... it's a process.

Closer to the topic ... non-dairy "cheese" could be eaten with meat, since it is not actually dairy; likewise, real cheese could be eaten with fake meat, because it is not actually meat. Some people might not be personally comfortable doing so, but it would be halachically permissible.
